Inflector Explained

What makes Inflector the most effective window insulation ?

Windows allow outside visibility, fresh air and provide natural day light for our homes and buildings but due to their transparency windows are also the weakest element of the building envelope thermally speaking. This weakness results in a major drain on the buildings HVAC system and causes energy bills to increase during the peak seasons of the year. Inflector addresses each and every thermal performance issue created by windows very effectively while maintaining the original purpose for having them in the first place.

Inflector is an engineered solution to window heat transfer issues. Inflector works by three main principals; Reflection, Absorption, and Insulation. Inflector is a product that is fitted on the inside of the window, this allows for a much longer in service lifespan of the product that to date is 30 years and counting. It does not matter what type of window or glazing option is currently being used, Inflector will improve the thermal performance dramatically. Inflector can be installed as a reversible panel, reversible roller blind or vertical blinds.

Summer mode / Reflection

Inflector is able to reflect heat due to the aluminum coating applied to one side of the material. Aluminum is a superb reflector of both solar and radiant heat. This principle is used successfully by many entities including NASA for their space program, by firefighters as an emergency tent, and by car manufacturers to reject heat produced by the engine. This same principle works for the windows by reflecting both heat produced directly by the sun and radiant heat from outside objects back to the outside environment. Heat rejected out means it does not have to be removed by the buildings A/C system. This results in a reduction of electricity consumption, and at times, even smaller A/C unit sizing.

Winter mode / Absorption / Reflection

The reverse side of the inflector material is coated with a carbon black coating. This coating allows heat to be absorbed by the sun and re-radiated into the room reducing the need to create heat with the buildings A/C or other heating source. With the aluminum surface of the product now facing into the building, heat created during the day or generated by your A/C is reflected by the aluminum surface back into the building which retains the heat rather than letting it escape through the glazing. Studies from the John Yellot Solar Laboratories in the US have proven that the inflector can produce 2,096 BTU/hour in a 16 square foot window area – the equivalent to a 600w electric floor heater. In Australia I have been told by experts that this figure would be 800 or 900 W / m² due to our higher solar irradiance levels.


The third way inflector protects is truly what sets this product apart from any other window product. The material is completely coated in a UV polymer. This polymer blocks 92% of harmful ultraviolet rays protecting carpet, furniture and pictures etc from the damaging effects of UV. More importantly however, the sealing polymer does not allow air to pass through the material. Trapping air between the inflector material and the glass of the window successfully insulates the window, increasing the thermal protection and insulation value of the building envelope. Additionally, this results in a significant reduction of infiltration issues. Old windows that suffer from air infiltration need not be replaced anymore, the problem can be resolved using the internal panel method of installation. This method seals the framework around the window. This means moisture and the increased BTU content associated with moisture, doesn’t get into the building. Once again, what doesn’t get in – does not have to be removed by the buildings A/C system.


Because the panels are held in place by a magnetic or channel framework, they can be removed and switched around at will. Because of the three means of protection provided by the inflector material, hot/cold spots are eliminated, occupants are more comfortable, and the energy bill is reduced saving the owner money. Lastly, since the product is see through, light still enters the window; visibility remains for the occupants on the inside and the aluminum coating even provides privacy for the buildings occupants during the day.

The following information gives an overview of the testing that has been conducted over the years by the many different testing agencies and laboratories. Testing reports are available for review.
